Mercedes-AMG GT R Roadster: UK prices and specs revealed

Mercedes-AMG GT R Roadster

Range-topping 577bhp version of drop-top AMG goes on sale, with prices starting at £178,675

The flagship version of the Mercedes-AMG GT Roadster, the hardcore, limited-run R model, is now on sale, priced from £178,675.

Representing a £34,400 price increase over the GT C Roadster and a £30,000 increase over the GT R coupé, it’s available to order now, with first deliveries expected in the autumn.

Revealed back at the Geneva motor show and limited to just 750 units, the GT R Roadster shares its twin-turbocharged 4.0-litre V8 engine with the GT R coupé. This sends 577bhp and 516lb ft  to the rear wheels via a seven-speed dual-clutch automatic gearbox.

Mercedes quotes a WLTP combined fuel economy figure of 22.6mpg and CO2 emissions of 284g/km. 

The GT R Roadster can hit 62mph from rest in just 3.6sec and reach a top speed of 197mph. That sprint time matches that of the GT R coupé, and the top speed is just 1mph shy of the fixed-roof model.

The aggressive styling of the coupé also translates to the Roadster, including the large fixed rear wing, while the likes of the coilover suspension and adjustable dampers – tuneable through several different driving modes – and rear-wheel active steering, also feature, giving the GT R Roadster a very similar dynamic spec to the GT R coupé.  

The aerodynamic package is also carried over, including the front lip spoiler, active aero front grille and large double rear diffuser that houses the tail-pipes. A wider track than the GT C Roadster allows for fitment of the larger lightweight 19in front, 20in rear alloy wheels, shod in Michelin Pilot Sport Cup 2 tyres and sized 273/35 front and 325/30 rear, while also improving stability.  

The three-layered fabric roof from the rest of the GT Roadster range carries over unchanged to the GT R Roadster. The model weighs 1710kg, an increase of 80kg over the GT R coupé. Rigidity improvements to mitigate the loss of strength in the GT’s conversion from coupé to convertible include thicker sill elements, an additional dashboard support and an aluminium cross-member integrated into the rear bulkhead that supports the fixed roll-over bars.

Lightweight options include composite brakes and a two-stage carbonfibre pack for various trim elements. 

Each of the 750 models sold will have a bespoke badge on the centre console depicting that car’s number in the production run. The Porsche 911-rivalling GT range now runs to 16 versions, including hard and soft-top road cars and racing models.
